Definitions

  • the heat pump 101 provides heating or cooling according to a predetermined or user-defined fixed-value of leaving water temperature (LWT).
  • the heat pump adjusts cooling capacity based on entering water temperature (EWT) and LWT in order to maintain the associated LWT.
  • the water pump 102 controls water flow based on pressure drop across the fan-coil units 120.
  • the three-way valve 103 by-passes surplus water flow to maintain minimum water flow required by heat pump 101 .
  • the valve position and the fan speed of each FCU may be used for controlling a different conditioned space's temperature.
  • a method of HVAC system control includes monitoring valve positions of proportional valves associated with individual heat exchangers of the HVAC system, monitoring return air temperatures associated with the individual heat exchangers of the HVAC system, determining a new fluid pressure set-point and a new fluid temperature pressure set-point for the HVAC system based upon the monitoring, and providing the new fluid pressure set-point and the new fluid temperature set-point to the HVAC system.

Abstract

L'invention porte sur un système, qui comprend une pompe à chaleur configurée de façon à adapter la température d'un fluide de travail à un point de consigne de température de fluide, une pompe de fluide en communication fluide avec la pompe à chaleur par l'intermédiaire du fluide de travail et configurée de façon à adapter la pression/l'écoulement du fluide de travail à un point de consigne de pression/écoulement de fluide, au moins un échangeur de chaleur en communication fluide avec la pompe de fluide, et un dispositif de commande de supervision en communication par signaux avec le ou les échangeurs de chaleur, la pompe de fluide et la pompe à chaleur. Le ou les échangeurs de chaleur comprennent une vanne proportionnelle et un dispositif de mesure de température d'air de retour, configuré de façon à réguler la température d'air de retour, associés à ceux-ci. Le dispositif de commande de supervision est configuré de façon à faire varier le point de consigne de température de fluide et à faire varier le point de consigne de pression/écoulement de fluide sur la base d'une position de la vanne proportionnelle et de la température d'air de retour.
